Abstract

For sleeve joints between concrete-filled circular steel tubular column and steel beam, authors carried out the monotonic static loading tests by using the T-shaped joint specimens, and have proposed an equation for estimating the ultimate strength. However, an application of the equation to an actual structure needs to consider the effects of cyclic loading and the diaphragm, including the application of the proposed method to the cross-shaped joint. Then, in addition to the monotonic static loading tests, the static loading tests by using the T-shaped joint specimens were carried out in order to investigate the effects of loading method and the diaphragm. Moreover, the monotonic static loading tests by using the cross-shaped joint specimens were also carried out. The test results indicate that the loading method (cyclic or monotonic) and a diaphragm affect on the ultimate strength, and that the application of the proposed method to the cross-shaped joint is promising.
